Abstract

This paper examines UK mortgage refinancing around the 23 September 2022 mini-budget interest rate shock, exploiting predetermined expiry dates of discounted two and five year fixed-rate mortgages. We find: (a) a shift toward two-year fixes, even though they priced above five-year mortgages; and (b) deleveraging, with a 200 basis points rate rise linked to a 2–3 percentage points drop in average loan to value ratios. Although the adjustable-rate mortgage share increased, most borrowers still chose the pricier two-year fix, consistent with seeking rate risk protection plus near-term flexibility for equity extraction if rates fall, an interpretation supported by evidence that near-term equity extraction is likelier under two than five-year loans.
